Suggest Remedy For Back Pain Post Antibiotic Treatment For Kidney Infection

Im having back pain, feels like kidney pain. There was plus 1 protein in my urine the last time i went to the doctor, so they put me on unit-biotics thinking it was a kidney infection. I finished the antibiotics and the pain is still here. Its not always very strong, but comes and goes. I have had a bad kidney infection before and it doesn't feel like that.
